Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to shatter into small granular chunks instead of splintering into jagged shards as ordinary annealed glass does. The granular chunks are less likely to cause injury.
No tong marks on the glass as adopts the horizontally tempering process.
5 times harder than ordinary annealed glass.
Once breakage occurs, the glass disintegrates into small cubical fragments which are relatively armless to human body.
It withstands abrupt change of temperature. For example, a piece of 5mm tolerate the temperature variations within the range of 200°C.
Tempered glass should under go heat soak test to improve safety in use.
Thickness: 3-19mm
Size: Min size 300*200mm,Max size 3300*15000mm
Tempered glass is used for its safety and strength in a variety of applications, including passenger vehicle windows, shower doors, aquariums, architectural glass doors and tables, refrigerator trays, mobile phone screen protectors, bulletproof glass components, diving masks, and plates and cookware.
